Auckland Stormwater Channels, Sumps and Drainage Concrete
Concrete channels, sumps, catchpits and drainage structures that move water away and protect your site.
Stormwater Channels, Sumps and Drainage Concrete in Auckland
Good stormwater control protects yards, slabs and buildings from standing water and scour. We build concrete channels, sumps, catchpits and drainage structures across Auckland, set to accurate grades so water is collected and moved away cleanly.
We excavate and prepare the ground, place reinforcement and pour structures to the engineer design and falls required. Channels and catchpits are tied into your stormwater system, and surrounds are finished to suit traffic. We own our diggers and trucks, so the drainage and the concrete are handled by one team.

Stormwater Concrete Services in Auckland
Channels, Sumps and Headwalls
We build concrete stormwater structures across Auckland, including channels, sumps, headwalls, kerbs, swales and detention areas, supporting subdivisions, commercial sites and rural properties that need reliable water management and compliance.
Accurate Levels and Falls
Stormwater systems must perform in heavy rain, so we form and pour to accurate levels and falls, using reinforced concrete and carefully placed joints that hold under flow and loading.
Built to Council Specs
We work to engineer drawings and Auckland Council requirements, coordinating pipes, inlets, outlets and connections so each structure fits into the wider drainage network without leaks, blockages or costly rework.
Erosion-Resistant Structures
Concrete channels, aprons and spillways resist erosion, scour and ongoing wear, protecting embankments, driveways and hardstand from water damage and reducing ongoing maintenance compared with unlined drains or basic surfaces.
Earthworks and Concrete Combined
Our own diggers, trucks and compaction equipment handle excavation, bedding and backfill, which is vital for drainage performance, and one team manages the earthworks and concrete from start to finish.

Stormwater Concrete Experts in Auckland: How We Work
We own our diggers, trucks and compaction equipment, so the groundwork and the concrete are handled by one team from start to finish.
Site visit and quote
We review the engineer drawings, levels and council requirements, check access, then provide a quote.
Excavation and subgrade
We excavate to accurate levels and compact the bedding, which is vital for drainage performance.
Formwork and reinforcement
We set formwork, inlets, outlets and reinforcement to the drawings, tying into the wider network.
The pour
We place the concrete to precise levels and falls for channels, sumps, headwalls and kerbs.
Finishing and curing
We finish durable, erosion-resistant surfaces, then cure the concrete for lasting strength.
Handover
We complete a final check, backfill, tidy the site and advise when the structure is ready.

Frequently Asked Questions
Can you tie new drainage into our stormwater system?
Yes. We build channels, sumps and catchpits and connect them to your existing stormwater system to the design provided.
How do you get the falls right?
We set structures to accurate grades so water flows to the collection points rather than pooling, following the engineer design for the site.
Do you pour catchpits and manhole surrounds?
Yes. We pour catchpits, sumps and surrounds, and can finish them to carry vehicle traffic where needed.
Can you combine this with a yard or slab pour?
Yes. We often build the drainage and the slab together, so the falls, channels and surface all work as one system.
Do you handle the excavation as well?
Yes. We own our diggers, trucks and compaction equipment, so the earthworks and the concrete are delivered by one team.
